Contoured Model Maps
Select a pre-defined region OR a map center location(ICAO ID, WMO Number, or lat,lon) plus zoom factor, map size, model, level, variable, contour interval, contour type, forecast time, model run for map, and the type of page:
Notes:
- The zoom feature does not work with pre-defined regions
- The first four map sizes work well for most regions with a few exceptions. The 1024x480 or 1280x600 sizes work best with the mercator tropical region maps. The 640x740 or 800x925 work best for the hemispheric maps. The 640x388, 760x460, 1024x620, or 1280x775 the global map projection.
- Not all options and times apply to every model. Blank maps result if the requested data are not available.
- For overlays - only necessary to set overlay and change the other entries that differ from the underlay.
- If the "latest" model data option doesn't work, not all new model data may have been received. In which case, try the "previous" option.
- Model data is only kept for approximately 24 hours.
